    Functional exploration of heterotrimeric kinesin-II in IFT and ciliary length control in Chlamydomonas

    Shufen Li, Kirsty Y Wan ... Junmin Pan
    Experimental and modelling analyses suggest a non-linear scaling relationship between IFT velocity and ciliary length that can be accounted for by limitation of the motors.

    Dynamics of the IFT machinery at the ciliary tip

    Alexander Chien, Sheng Min Shih ... Ahmet Yildiz
    During intraflagellar transport (IFT), kinesin-II dissociates from IFT trains at the flagellar tip and its diffusion in flagella serves as a negative feedback mechanism that facilitates flagellar length control in Chlamydomonas.

    The master cell cycle regulator APC-Cdc20 regulates ciliary length and disassembly of the primary cilium

    Weiping Wang, Tao Wu, Marc W Kirschner
    The anaphase promoting complex (APC) has an essential role in ubiquitin-mediated proteolysis in the disassembly of cilia.

    CEP78 functions downstream of CEP350 to control biogenesis of primary cilia by negatively regulating CP110 levels

    André Brás Gonçalves, Sarah Kirstine Hasselbalch ... Lotte Bang Pedersen
    Analysis of mutant cells combined with biochemical experiments reveals that CEP78 is recruited to the centrosome by CEP350 and regulates ciliogenesis and ciliary length control through CP110-dependent and CP110-independent mechanisms, respectively.

    Length-dependent disassembly maintains four different flagellar lengths in Giardia

    Shane G McInally, Jane Kondev, Scott C Dawson
    Giardia, a multi-ciliated parasitic protist, maintains four different flagellar lengths by balancing flagellar length-independent IFT-mediated assembly with length-dependent kinesin-13 mediated disassembly.

    Ciliary transcription factors and miRNAs precisely regulate Cp110 levels required for ciliary adhesions and ciliogenesis

    Peter Walentek, Ian K Quigley ... Richard M Harland
    At optimal concentrations, the ciliary inhibitor Cp110 promotes ciliogenesis by localization to previously uncharacterized sites at the basal body, where it recruits ciliary adhesion complexes that mediate basal body interaction with F-actin networks.

    Motility and microtubule depolymerization mechanisms of the Kinesin-8 motor, KIF19A

    Doudou Wang, Ryo Nitta ... Nobutaka Hirokawa
    The structural and functional analysis demonstrates the mechanism of dual functional, motility and microtubule depolymerization in a unique motor, KIF19A.

    Testing the ion-current model for flagellar length sensing and IFT regulation

    Hiroaki Ishikawa, Jeremy Moore ... Wallace F Marshall
    A model for flagellar length control based on calcium influx is rejected based on quantitative measurements in Chlamydomonas cells.

    The novel ciliogenesis regulator DYRK2 governs Hedgehog signaling during mouse embryogenesis

    Saishu Yoshida, Katsuhiko Aoki ... Kiyotsugu Yoshida
    DYRK2 regulator governs the mammalian ciliogenesis to maintain proper embryogenesis via activation of the Hh signaling during development in vivo.
